Exam 3: General Theories of Operation

A(n)____________________ converts hydraulic pressure to mechanical movement.

A compound planetary gear set contains two complete planetary gear sets.

The ____________________ carries the driving gear.

Technician A says that some newer transmission designs incorporate as many as eight forward speeds. Technician B says the main reason for an overdrive gear is to increase vehicle performance. Who is correct?

Automatic transmission problems are usually caused by one or more of the following conditions: 1. Poor engine ____________________ 2. Problems in the _____________________ system 3. Problems with _______________________ controls 4. _________________ problems in the transmission 5. Improper ________________ of internal parts and/or linkages

The ____________________ directly controls mainline pressure.

Technician A says it is necessary to identify any and all non-factory installed electrical accessories when inspecting a vehicle. Technician B says non-factory installed electrical accessories may cause the system to not operate properly. Who is correct?

When checking for stored DTCs in the computer systems, the following steps are scrambled. Rearrange the steps to indicate the proper order of steps to follow. 1. Calibrate the scan tool. 2. Connect the scan tool. 3. Set the scan tool to retrieve DTCs. 4. After a test drive, check to see if the codes were reset. 5. Record all recovered DTCs. 6. Take the vehicle for a test drive. 7. Clear the codes.

Which of the following is true of the VIN?

Which of the following is true of solenoids?

List at least six conditions, that may exist when the problem occurs, that will be of help in diagnosing a transmission problem.

Some newer designs of transmissions and transaxles may be equipped with two fluid filters.

Explain the function of reaction members.

Most late-model transmissions use an ____________________  to regulate transmission or transaxle fluid line pressure.

The ____________________ uses vanes and a cam ring to generate oil pressure.

​On vehicles with the electronic throttle actuator control (TAC), the _______________ tells the ECM/TCM what the driver desires for throttle position.

Technician A says planetary gears provide different gear ratios needed to move the vehicle. Technician B says automatic transmissions and transaxles must have at least three planetary gear sets. Who is correct?

Technician A says when there is a delay or slip as the transmission shifts into any forward gear, a slipping rear clutch is indicated. Technician B says a slipping front or forward clutch is indicated if the shift for all forward gears is delayed. Who is correct?

​ A scan tool is needed to check fluid level in transmissions without a dipstick.

The ____________________ moves according to the position of the throttle.
